WCC Server validation failures can happen if the EEM settings within AE are not consistent with those listed in WCC's AE server definition.
Example: in autosys_secure AE lists that it is in NATIVE security mode while in WCC's server definition it shows AE as being EEM Enabled.
Errors may also occur if AE is pointing to a different EEM than WCC, where the two EEM's are not configured in a trusted / HA mode.
Review autosys_secure's EEM settings and WCC's EEM settings.
